We bought this trimmer so we could cut an 8.5 x 11 piece of paper so we can make small story books for our autism clinic. I am finally tired of dealing with this useless product and should have taken it back months ago. I have attached pictures so you can see what it does to your plain copy paper as you try to get a clean cut and this is with no more than 3 pieces of paper. This paper trimmer will also mess up with only one sheet of paper and does not even come close to the 15 sheet capacity. On top of that, the laser is rather useless as it doesn't even line up correctly with the cut edge even if you adjust it per the written instructions. Next issue is that one of the cut edges gets rolled up after you trim the paper. This has been happening since I bought the trimmer and I thought it was operator error, but I have tried slow cut, fast cuts and this trimmer just cannot do what it was labeled for.

Laser does work but I had to use new batteries (the ones that came with it didn't work); laser aligns great at the far edge where you need it most, just remember the laser is a guide and you should use the ruler marks too :)

Works fine but there are no detailed instructions in the pamphlet. I still haven't gained access to the battery compartment, it shouldn't be this difficult to get into. I have no idea how the laser works since there are only illustrations in the pamphlet and no details in the form of written instructions.
